2023 electron最新最简版windows、mac打包、自动升级详解-编程知识

这里我将讲解一下从0搭建一个electron最简版架子，以及如何实现打包自动化更新

之前我有写过两篇文章关于electron框架概述以及常用api的使用，感兴趣的同学可以看看

Electron桌面应用开发2

搭建electron

官方文档：https://www.electronjs.org/zh/

在这里插入图片描述
只需要三个文件就可以跑起来electron

创建一个文件目录

mkdir my-electron-app && cd my-electron-app
yarn init

然后，将 electron 包安装到应用的开发依赖中。

yarn add --dev electron

{"name": "my-electron-app","version": "1.0.0","description": "Hello World!","main": "main.js", // 入口文件"author": "Jane Doe","license": "MIT","scripts": {"start": "electron ."},"devDependencies": {"electron": "^27.0.3",}
}

main.js

const createWindow = () => {const win = new BrowserWindow({width: 800,height: 600})win.loadFile('index.html') // 加载index.html
}

index.html

<!DOCTYPE html>
<html><head><meta charset="UTF-8"><!-- https://developer.mozilla.org/zh-CN/docs/Web/HTTP/CSP --><meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'"><title>你好!</title></head><body><h1>你好!</h1>我们正在使用 Node.js <span id="node-version"></span>,Chromium <span id="chrome-version"></span>,和 Electron <span id="electron-version"></span>.</body>
</html>

yarn start就可以启动起来，这是最简版的框架

配置打包、自动升级

这里强调一下

做mac的打包需要开通苹果开发者账号，购买证书，打包需要签名，这里购买和配置的流程很复杂就不做过多赘述，都搜的到。

其实windows也需要签名证书，但是不提供也可以打包

打包和自动升级用到了官方提供的两个工具

打包：electron-builder
升级：electron-updater

electron-builder官方文档地址：https://www.electron.build/configuration/win#WindowsConfiguration-certificateSubjectName

如果觉得英文看着不方便，有大神中文总结了一下，地址：https://blog.csdn.net/qq_38830593/article/details/89843722

首先下载这两个库：
yarn add electron-builder -D
yarn add electron-updater

package.json里做参数配置

看build参数，各个参数对照着官方文档

}

main.js

const { app, BrowserWindow, ipcMain } = require('electron')
const { autoUpdater} = require('electron-updater')
const os = require('os')
const logger = require('electron-log')//打印log到本地
logger.transports.file.maxSize = 1002430 // 10M
logger.transports.file.format ='[{y}-{m}-{d} {h}:{i}:{s}.{ms}] [{level}]{scope} {text}'
logger.transports.file.resolvePath = () => './operation.log' //打印在你安装的软件位置，autoUpdater.autoDownload = false //这个必须写成false，写成true时，我这会报没权限更新，也没清楚什么原因// 将创建窗口独立成一个函数

</script>

执行升级

执行yarn build之后，会生成安装包和 yml文件
在这里插入图片描述
yml文件是内部做检测更新使用

version: 1.0.0
files:- url: electron-test-1.0.0-arm64-mac.zipsha512: YFebRa4hFb0eq7JBHtIbe6zpEm59b3uR0NaKJJaY5M7G7ZfCoFIWJl/N3cDzSvPK1vWSgeGTRwxteHmwV7PXBQ==size: 88974676- url: electron-test-1.0.0.dmgsha512: ZToMM68na/NWbvYpqqEk3Ej0LzsDoyEYd9rW2qHIaq5FxU/HHNntzX2KiSv002WcLX6aQgLSgh37gvUJytvOpQ==size: 92423278

releaseDate: '2023-11-05T08:56:32.685Z'

我们需要把这三个文件放在对象存储服务器上
在这里插入图片描述
只要提供的更新地址拼接上 latest-mac.yml文件的可以访问到就可以

这样就可以做更新了

如果做测试，本地启动一个服务

 //更新连接autoUpdater.setFeedURL('http://127.0.0.1:5500/build')

这里指向本地就可以，打包生层的文件放在build目录下一样测试
